description The invention relates to an Ag (at) AgX (at) TiO2/attapulgite material and application thereof, a preparation method of the Ag (at) AgX (at) TiO2/attapulgite material comprises the following steps: A, mixing attapulgite powder, Arabic gum and modified starch, granulating, and calcining at 500-700 DEG C for 1-3 hours to obtain a raw material A; b, taking a NaX solution, wherein X is Cl, Br or I; adding polyethylene glycol 400 as a dispersing agent, then adding oil-soluble nano TiO2, stirring and dropwise adding AgNO3 to obtain an AgX-coated TiO2 precipitate, filtering, drying at the temperature of 100-110 DEG C, and grinding into fine powder to obtain AgX-coated TiO2 fine powder; c, the AgX-coated TiO2 fine powder is subjected to ultraviolet irradiation, and after ultraviolet irradiation is completed, Ag-coated AgX-coated TiO2 is obtained and serves as a raw material B; and D, mixing the raw material A and the raw material B according to a mass ratio of 1: (0.01-0.1), and carrying out heat treatment at 40-60 D
